Part Number: TPS568230

Hello,

I simulated this circuit in WBench and I'm seeking:

- a schematic review and verification of these calculations

- Why WBench suggested ECO Mode operation?

Thanks

Hi,

1. You can input your requirements and Webench will create a schematic for your reference.

2. No, Webench won't do this recommendation, using Eco-mode or FCCM or OOA mode is configured by the user. Below is the configuration method:

Let me know if you have more questions.

Thanks, Which mode is recommended for a device that is estimated to consume 7A at 5V, and it is powered by an adaptor (No batteries and no power saving requirements)?

Hi,

For heavy load, no matter Eco-mode or FCCM or OOA mode, device behaviors are same .

For light load, Eco-mode and OOA have higher efficiency but larger Vo ripple, while FCCM has smaller Vo ripple but lower efficiency.
